Nirvana--which I call Universal Mind--is an illusion, but it's still more real than the astral and of course the physical. So if you're going to call it an illusion, include the rest of creation, because the Ruler of this world is Universal Mind--aka, The "Causal" plane.
The physical is just a projection of the inner worlds. Plato had it right in "The Cave".
